Captive birds exhibit greater foraging efficiency and vigilance after anti-predator training.

This article focuses on evaluating the effects of anti-predator training on the risk-analysis and foraging behaviors of captive-reared American robins (Turdus migratorius) to improve conservation translocation outcomes. Using a giving up density (GUD) experimental design, the study found that after anti-predator training involving exposure to a live red-tailed hawk and predator cues, robins exhibited increased vigilance (notably skygazing behavior) and improved foraging efficiency in safer foraging patches, indicated by lower GUD values. While increased vigilance across all patches was observed, the study highlights the need for further research to balance vigilance and foraging to avoid potential fitness costs. The authors suggest that combining GUD tests with behavioral analyses offers a valuable tool for wildlife managers to assess and refine anti-predator training protocols before releasing captive-bred birds into the wild.
